I'll share my experience where the driver reactions to a BMW are better than my other car, a Prius (long commute).
I get tailgated all the time in the Prius and I'm not hypermiling, I'm doing 10mph over the limit and not blocking traffic.
When I drive the same way in the M240i, I hardly ever get tail gated.
It doesn't matter how fast you drive in a Prius, people just assume you're going slow
